# Backend Startup Fix ✅

## Problems Found

1. **Last Warning**: One more unused `HashMap` import in `container/src/podman_client.rs`
2. **Backend Crash**: Permission denied when trying to create `/var/lib/archipelago`

## Root Cause

The backend default configuration tries to create `/var/lib/archipelago` which requires root permissions. In development, we need to use `/tmp/archipelago-dev` instead.

## Fixes Applied

### 1. Removed Last Warning ✅

**File:** `core/container/src/podman_client.rs`
- Removed unused `std::collections::HashMap` import

**Result:** ZERO warnings now! 🎉

### 2. Fixed Backend Startup ✅

**File:** `scripts/dev-start.sh`
- Added environment variable exports before starting backend
- Sets `ARCHIPELAGO_DATA_DIR=/tmp/archipelago-dev`
- Sets dev mode and other required configs

**Also Created:** `setup-env.sh` (optional script to create `.env` file)

## How to Run Now

### Quick Start (Automatic)

```bash
cd /Users/dorian/Projects/archy
./scripts/dev-start.sh
```

Choose option **2** (Full stack)

The script now automatically:
- Sets all required environment variables
- Uses `/tmp/archipelago-dev` (no permissions needed)
- Starts backend with correct config
- Waits for backend to be ready
- Starts frontend

### Alternative: Manual Setup (Optional)

If you want a persistent `.env` file:

```bash
./setup-env.sh
./scripts/dev-start.sh
```

## Environment Variables Set

```bash
ARCHIPELAGO_DATA_DIR=/tmp/archipelago-dev
ARCHIPELAGO_DEV_DATA_DIR=/tmp/archipelago-dev
ARCHIPELAGO_DEV_MODE=true
ARCHIPELAGO_BIND=127.0.0.1:5959
ARCHIPELAGO_LOG_LEVEL=debug
ARCHIPELAGO_PORT_OFFSET=10000
ARCHIPELAGO_BITCOIN_SIMULATION=mock
```

## Test It

1. **Rebuild (to remove last warning):**
   ```bash
   ./clean-rebuild.sh
   ```
   Expected: **ZERO warnings!**

2. **Start dev server:**
   ```bash
   ./scripts/dev-start.sh
   ```
   Choose option 2

3. **Check backend log:**
   ```bash
   tail -f /tmp/archipelago-backend.log
   ```
   
   Should see:
   ```
   🚀 Starting Archipelago Bitcoin Node OS
   📁 Data directory: /tmp/archipelago-dev
   🌐 Server listening on http://127.0.0.1:5959
   📡 RPC API: http://127.0.0.1:5959/rpc/v1
   🔌 WebSocket: ws://127.0.0.1:5959/ws
   ```

4. **Open browser:**
   ```
   http://localhost:8100
   ```

## What Changed

### Before ❌
- Backend tried to use `/var/lib/archipelago` (permission denied)
- Crashed immediately on startup
- Dev server hung waiting for port 5959

### After ✅
- Backend uses `/tmp/archipelago-dev` (always writable)
- Starts successfully in ~1 second
- Dev server detects backend and starts frontend
- Full stack is live!
